Working principle:

Stainless Steel End Caps for PVC Pipe Internal Pressure Testing

These stainless steel end caps serve as dedicated sealing components for test specimens during PVC pipe internal pressure testing procedures. High-temperature resistant silicone sealing rings are pre-embedded in the precision-machined seal grooves of the stainless steel caps; during assembly, the integrated metal compression rings exert uniform force on the silicone sealing rings.

The silicone O-rings deform elastically under external compression, creating a tight, leak-proof seal between the end caps and pipe ends—this structural design ensures the integrity of the pressure testing environment and eliminates data inaccuracies caused by pressure leakage.

Structural composition:

The core supporting components for the testing system include a semicircular base, sealing ring, pressure ring, clamp, fastening bolts, compression bolts, and vent valve—all engineered to ensure stable clamping and reliable sealing during pipe internal pressure testing.

Application:

These components serve as dedicated sealing assemblies for specimens of PVC, PE, PP-R, ABS, and composite pipes, facilitating a full spectrum of pipe performance evaluations including hydrostatic pressure testing, burst testing, and negative pressure testing.

Fixture structure:

This component adopts a semi-circular trough design, which facilitates hassle-free assembly, ensures leak-tight sealing performance, and enables streamlined operation during testing procedures.

Custom diameter specifications are available to meet customer-specific requirements, with the component material options including 304 stainless steel or carbon steel to suit diverse application scenarios and budget considerations.

FAQ:

Q1: What is the adjustable range of pipe diameters that the hydrostatic pressure testing fixture can accommodate, and does it support custom specifications?

A1: The standard model of this fixture is adaptable to pipe diameters ranging from Φ8 mm to Φ1800 mm. For non-standard pipe sizes beyond this range, we provide customized processing services according to customer drawings and test requirements, ensuring a perfect fit with the tested pipework.

Q2: What are the material options for the hydrostatic pressure testing fixture, and how do they differ in application scenarios?

A2: Two primary material options are available: 304 stainless steel and carbon steel. The 304 stainless steel variant is corrosion-resistant, making it ideal for testing pipes with acidic/alkaline media or for long-term use in humid laboratory environments. The carbon steel variant offers cost-effectiveness and high structural rigidity, which is suitable for routine hydrostatic tests of ordinary plastic pipes in dry working conditions.

Q3: What is the maximum sealing pressure rating and temperature resistance limit of the hydrostatic pressure testing fixture?

A3: The fixture can maintain a reliable, leak-free seal under a maximum test pressure of 16 MPa, fully matching the pressure range of mainstream hydrostatic testing machines. Its temperature resistance range is -20℃ to 120℃, which covers the standard test temperature interval (15℃–95℃) of plastic pipes and allows for short-term high-temperature testing scenarios.

Q4: How does the fixture ensure the consistency of clamping force during testing, and is it compatible with both automatic and manual testing machines?

A4: The fixture adopts a bolt-group uniform compression structure, which can apply balanced clamping force around the pipe circumference to avoid local deformation of the pipe end caused by uneven force. It is fully compatible with both automatic hydrostatic testing machines (via PLC-controlled pressure adjustment) and manual testing machines (via torque wrench operation), with no need for additional adapter parts.

Q5: What is the service life of the fixture’s sealing ring, and what types of sealing rings are available for different test media?

A5: Under normal use conditions, the high-temperature resistant silicone sealing ring has a service life of 500+ test cycles.
